remove dust, etc., from the
lens surface. Then use a
soft, dry cloth to wipe the
lens gently.

The battery power is low. Even if the lamp lights, the

shaken severely while the
Image Stabilizer is operating,
there is a strange noise.
The batteries are exhausted. Replace the batteries with

There are air bubbles in the
lens.
Air bubbles may form in the
lens when the atmospheric
pressure is low in airborne
airplanes or on high
mountains. This is not a
abnormality.
The air bubbles will usually
disappear after about a
week, depending on the
atmospheric pressure and
operating conditions.
